Velikaruvai (Neltuma juliflora)

Velikaruvai, seemai karuvelam in Tamil and vilayati babul in Hindi, is mesquite, a thorny tree from tropical America that colonial and later governments planted across dry India for fuel and to hold sand. It spread far beyond the plantings and now forms dense thickets in Tamil Nadu, Gujarat, Rajasthan and Andhra Pradesh, displacing native grassland such as the Banni of Kutch. Botanists recently moved it from Prosopis to Neltuma.

Paired straight thorns sit at the nodes.

The leaves are feathery and twice-divided into many small leaflets.

Pale yellow flowers form slender, catkin-like spikes.

The pods are long, flat, yellowish and sweet, and are eaten by goats and cattle, which spread the seeds.

Modern notes on Velikaruvai

It is one of India’s most damaging invasive trees, lowering groundwater and crowding out native grasses and trees.

The Madras High Court ordered its removal from Tamil Nadu in the 2010s, a programme still under way.

Livestock that eat large amounts of pods can develop tooth and nerve problems.

Its pollen is a cause of allergy and asthma in dry regions.

Velikaruvai safety

Its long thorns cause deep, slow-healing wounds; wear thick boots and gloves when clearing it. People with pollen allergy may react during flowering.

Ecology and sourcing

It is native to Mexico, Central America and northern South America.

Seeds pass unharmed through animals and sprout readily in dung.

Clearing it is hard because stumps resprout unless the roots are removed.
